Synthetic keys generate when two tables have quite one field in common. Generation of an artificial key considers bad because it indicates a nasty arrangement which could cause issues with handling data and conducting a correct analysis. there’s no ideal solution to resolve this problem aside from preventing the presence of quite one common field between tables.

Circular reference warning while loading data?

Circular references or looping happens once we connect one table to the opposite in additional than a method. This causes a logically impaired data model which we will fix by renaming the common fields etc.

Unable to pick data from an OLE DB connection?

Check the configuration details of the connection, it should be rightly configured or check if the connection string is correctly designed. Also, you’ll check if you’re logging in with the right details.

Unsupported non-ANSI character set?

Sometimes, the info files fetched using an OLE DB connection doesn’t support the characters, doesn’t encod in ANSI. to repair this problem, you want to fetch data files via a folder connection because it will handle more character codes.

When a connector isn’t working?

A connector does no work i.e. it’s unable to determine a knowledge connection because the connector isn’t installed properly. Check whether the installed connector is correct or not. just in case of a multi-node deployment, the connector must be installed on all the nodes. And, in some cases, the connector has got to be made compatible for Qlik Sense for it to figure .

Data doesn’t load even after execution of the info script?

Sometimes albeit the script executes with none error detection, the info doesn’t load. To resolve this, activate the debug option and check for any missing semicolons at the top of statements.

Showing error for the invalid path?

A file path can return as invalid if it doesn’t found within the system or if the name is greater than 171 characters as Qlik Sense only supports file names up to 171 characters.

If a date field doesn’t recognize as a date field?

If you load a date field during a table but it doesn’t recognize or read as a date field by the system within the sheet view. Then, open the info manager and attend the edit option and edit that table. Change the sector type so far or Timestamp and specify a date-time format.

Are tables not showing within the data manager?

If the info manager doesn’t show tables and their data, albeit they’re loaded into the script. Then attend the info manager and click on on Load Data option. this may reload the table, complete the info profiling and preparation then display the tables within the app.

Low disk space?

You might run out of disc space as all the loaded data caches in QVD files. to unravel this problem, delete the folder which contains all the QVD files from the source, C:\Users\\Documents\Qlik\Sense\Apps\DataPrepAppCache.

Qlik Sense Troubleshooting in Creating Visualizations

Cannot find your fields within the assets panel?

Possibly because you’re working during a published app where the publisher must haven’t allowed access to the fields.

Showing error message “The data contains invalid geometries which will not show on the map. Review your data for errors and check out again.”?

The geometric data (probably from a KML file) you’re using must not be within the correct format or have some errored and unsupported content. Check for the format and errors, correct them and reload the files.

Showing error message “The following locations couldn’t be found: . Review the values in your data and check out again.”?

Locations given by the users to be used in maps are sometimes not found and shown probably because they’re not spelled correctly, or the given location isn’t found within the Qlik Sense location database. To resolve this, check for any errors within the spellings, or add the coordinated of the situation manually if it’s not present within the QS database.

Showing error message “The following locations had quite one result: . Set a custom scope to clarify which locations to display.”?

If the situation you enter resembles other locations and returns multiple results. Then, you’ll specify additional details for that specific location to line it aside from others. We call this as setting a scope for the situation . Set the Scope for location choice to Custom and add additional details like city, state, country etc.

iii. Qlik Sense Troubleshooting in Discovering

Does not produce results upon searching?

Possibly this is often because the selections whose values you’re checking out are locked. Unlock the selections then search.

Showing error message “Incomplete visualization”?

Visualizations aren’t shown properly if you are doing not have access to a number of the info fields. Request the app administrator to grant you access to the restricted data fields.

Qlik Sense Troubleshooting in Exporting

Data cannot export completely?

You may have exceeded the file size limit. Make the file of the supported size then export it.

Cannot export a visualization as an image?

Possibly because the visualization is just too large in size to export. The permitted size is 2000 by 2000 pixels. If your image size exceeds this, then resize the image and check out to export it again.

Having blank spaces in situ of specific language characters?

Sometimes the characters of the languages like Japanese, Korean, Simplified Chinese, or Traditional Chinese doesn’t support within the fonts of stories. So, if you would like to display these fonts of various languages, then you’ve got to download the fonts then export the PDFs.

Data view table changing back to visualization after exporting?

This is because the info view doesn’t support exporting. you’ll select the Export data choice to export the info from each visualization instead.

The table doesn’t show the entire field after exporting?

Possibly because only the first fields retain after exporting then , you’ve got to recreate the calculated Total field again.

Qlik Sense Troubleshooting in Deployment

To troubleshoot the problems associated with deployment, you want to follow a procedure, so as to detect the difficulty properly. you’ll either solve the difficulty by yourself, using the log files otherwise you can call certain professional help. To detect the matter initially , attempt to find out things like What quite a drag is it? Is it a configuration problem, a component problem or a worldwide issue? are there any error messages? Did the system behave abnormally? during which component did the difficulty is occurring?

After finding answers of those questions, search for the log file respective of the component (engine, repository, proxy, and scheduler) during which the matter occurs. Then, compare the small print of a traditional log file with the small print of the log file which had recorded the info at the time of error or malfunction. From here, you’ll identify the difficulty and fix it.

Qlik Sense Troubleshooting in Administering

Troubleshooting the executive tasks uses the log files which stores system performance related information for all the kinds of operations happening in Qlik Sense. The log files keep a log of security operations, data loading, load balancing, distribution etc. If there’s a drag , which usually shows by error message generation, then you’ll search for the respective log file and detect the difficulty so as to further take the simplest troubleshooting step. All the problems generated, and therefore the troubleshooting methods suggested for them generally categorizes into use case sections. There are three such sections,

Procedure: Records the procedure or operation that’s being administered in Qlik Sense.
Success: This section has all the names of log files to which the small print of the procedures are written.
Errors: This section contains the list of all the possible errors related to different procedures.
